* Marvell MBus
Required properties:
- compatible: Should be set to one of the following:
marvell,armada370-mbus
marvell,armadaxp-mbus
marvell,armada370-mbus
marvell,armadaxp-mbus
marvell,kirkwood-mbus
marvell,dove-mbus
marvell,orion5x-88f5281-mbus
marvell,orion5x-88f5182-mbus
marvell,orion5x-88f5181-mbus
marvell,orion5x-88f6183-mbus
marvell,mv78xx0-mbus
- address-cells: Must be '2'. The first cell for the MBus ID encoding,
the second cell for the address offset within the window.
- size-cells: Must be '1'.
- ranges: Must be set up to provide a proper translation for each child.
See the examples below.
- controller: Contains a single phandle referring to the MBus controller
node. This allows to specify the node that contains the
registers that control the MBus, which is typically contained
within the internal register window (see below).
Optional properties:
- pcie-mem-aperture: This optional property contains the aperture for
the memory region of the PCIe driver.
If it's defined, it must encode the base address and
size for the address decoding windows allocated for
the PCIe memory region.
- pcie-io-aperture: Just as explained for the above property, this
optional property contains the aperture for the
I/O region of the PCIe driver.
* Marvell MBus controller
Required properties:
- compatible: Should be set to "marvell,mbus-controller".
- reg: Device's register space.
Two entries are expected (see the examples below):
the first one controls the devices decoding window and
the second one controls the SDRAM decoding window.
Example:
soc {
compatible = "marvell,armada370-mbus", "simple-bus";
#address-cells = <2>;
#size-cells = <1>;
controller = <&mbusc>;
pcie-mem-aperture = <0xe0000000 0x8000000>;
pcie-io-aperture = <0xe8000000 0x100000>;
internal-regs {
compatible = "simple-bus";
mbusc: mbus-controller@20000 {
compatible = "marvell,mbus-controller";
reg = <0x20000 0x100>, <0x20180 0x20>;
};
/* more children ...*/
};
};
** MBus address decoding window specification
The MBus children address space is comprised of two cells: the first one for
the window ID and the second one for the offset within the window.
In order to allow to describe valid and non-valid window entries, the
following encoding is used:
0xSIAA0000 0x00oooooo
Where:
S = 0x0 for a MBus valid window
S = 0xf for a non-valid window (see below)
If S = 0x0, then:
I = 4-bit window target ID
AA = windpw attribute
If S = 0xf, then:
I = don't care
AA = 1 for internal register
Following the above encoding, for each ranges entry for a MBus valid window
(S = 0x0), an address decoding window is allocated. On the other side,
entries for translation that do not correspond to valid windows (S = 0xf)
are skipped.
soc {
compatible = "marvell,armada370-mbus", "simple-bus";
#address-cells = <2>;
#size-cells = <1>;
controller = <&mbusc>;
ranges = <0xf0010000 0 0 0xd0000000 0x100000
0x01e00000 0 0 0xfff00000 0x100000>;
bootrom {
compatible = "marvell,bootrom";
reg = <0x01e00000 0 0x100000>;
};
/* other children */
...
internal-regs {
compatible = "simple-bus";
ranges = <0 0xf0010000 0 0x100000>;
mbusc: mbus-controller@20000 {
compatible = "marvell,mbus-controller";
reg = <0x20000 0x100>, <0x20180 0x20>;
};
/* more children ...*/
};
};
In the shown example, the translation entry in the 'ranges' property is what
makes the MBus driver create a static decoding window for the corresponding
given child device. Note that the binding does not require child nodes to be
present. Of course, child nodes are needed to probe the devices.
Since each window is identified by its target ID and attribute ID there's
a special macro that can be use to simplify the translation entries:
#define MBUS_ID(target,attributes) (((target) << 24) | ((attributes) << 16))
Using this macro, the above example would be:
soc {
compatible = "marvell,armada370-mbus", "simple-bus";
#address-cells = <2>;
#size-cells = <1>;
controller = <&mbusc>;
ranges = < MBUS_ID(0xf0, 0x01) 0 0 0xd0000000 0x100000
MBUS_ID(0x01, 0xe0) 0 0 0xfff00000 0x100000>;
bootrom {
compatible = "marvell,bootrom";
reg = <MBUS_ID(0x01, 0xe0) 0 0x100000>;
};
/* other children */
...
internal-regs {
compatible = "simple-bus";
#address-cells = <1>;
#size-cells = <1>;
ranges = <0 MBUS_ID(0xf0, 0x01) 0 0x100000>;
mbusc: mbus-controller@20000 {
compatible = "marvell,mbus-controller";
reg = <0x20000 0x100>, <0x20180 0x20>;
};
/* other children */
...
};
};
** About the window base address
Remember the MBus controller allows a great deal of flexibility for choosing
the decoding window base address. When planning the device tree layout it's
possible to choose any address as the base address, provided of course there's
a region large enough available, and with the required alignment.
Yet in other words: there's nothing preventing us from setting a base address
of 0xf0000000, or 0xd0000000 for the NOR device shown above, if such region is
unused.
** Window allocation policy
The mbus-node ranges property defines a set of mbus windows that are expected
to be set by the operating system and that are guaranteed to be free of overlaps
with one another or with the system memory ranges.
Each entry in the property refers to exactly one window. If the operating system
choses to use a different set of mbus windows, it must ensure that any address
translations performed from downstream devices are adapted accordingly.
The operating system may insert additional mbus windows that do not conflict
with the ones listed in the ranges, e.g. for mapping PCIe devices.
As a special case, the internal register window must be set up by the boot
loader at the address listed in the ranges property, since access to that region
is needed to set up the other windows.
